Hi!
The Payload structure section says the payload must contain a "timestamp" field that should describe the time when the event occurred. I suggest we use "occurredAt" instead because "timestamp" is a bit fuzzy and it may have different meanings.

So, the payload would look like:

{
  "type": "example.event",
  "occurredAt": "2022-11-03T20:26:10.344522Z",
  "data": {
    "foo": "bar",
    "fizzbuzz": 2
  }
}

What do you think? If you're ok with this change then I could come back with a pull request.
